POLE-BASE.

Specification of Letters Patent.

Application filed June 1, 1914. Serial No. 842,191.

To all whom it may concern:

Be it knownthat I, ALEXANDER BARBER, a citizen of the United States,residing at Edwardsville, in the county of Madison and State ofIllinois,have invented certain new and useful Improvements inPole-Bases, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention has relation to improvements in pole-bases; and it consistsin the novel features of construction more fully set forth in thespecification and pointed out in the claims.

In the drawings, Figure 1 is an elevation of a telegraph pole showing myinvention applied thereto; Fig. 2 is an enlarged vertical cross-sectiontaken through the concrete base on the line 2-2 of Fig. 1; Fig. is anenlarged horizontal section on the zigzag line 3-3 of Fig. 1; Fig. 4 isan elevation of a section of a picket fence showing my'invention appliedthereto; and Fig. 5 isa horizontal section on the line 5-5 of Fig. 4:.

The present invention is particularly directed to reinforced concretebases for supporting and anchoring telegraph, telephone and electricwire-carrying poles generally, although the same is eminently adaptedfor securing fence posts. The objects sought are to provide a base whichwill be practically permanent, not being affected or deteriorated by theelements; one which has provision for anchoring the pole against lateraldeflection; one which may be cheaply constructed, one which is strongand durable, and one possessing further and other advantages betterapparent from a det a1led description of the invention, which is asfollows:

Referring to the drawings, and for the present to Figs. 1 to 3inclusive, B, repre' sents asuitable concrete base preferably octagonalin cross-section and of the form of a truncated pyramid, and set in theground with a portion projecting above the surface of the ground,jtheupper end of said base formin a preferably flat or plane surface ortable for the support of the pole P. Stretched from pole to pole as wellunderstood in the art, are the electric wires to (which may betelephone, telegraph or electric light wires) said wires tying theseries of poles against deflection or tilting in the general directionof disposition of the wires, the terminal poles of the system beinganchored or braced against such deflection by any means known to theart. lVith these features my present improvement is notdirectlyconcerned, because such features are old, the inventionherein beingdirected in the main to details of construction which prevent lateraldeflection of the poles.

Assumingthat the present base B has eight faces, I secure to three ofthe faces on either side of, and contiguous to, the two remaining faceswhich are disposed transverse to the general direction of disposition ofthe wires, the bases of suitable straps 1, said basal portions beingprovided with openings or perforations through which are passed theouter terminal deflected ends or. nooks h of the concrete-reinforcingbars or rods or equivalent membersQ, said ends it being passed throughthe faces of the base B at points removed a suitable distance from theupper end of said base. These hooks It thus serve as anchors for thestraps 1, the latter being extended upwardly beyond the base and securedto the pole P by means of lag screws 3 as shown.

Embedded in the pole immediately beneath and in contact with each screw3 is a reinforcing metal block or plate 4 which prevents the screwssinking or cutting into the body of the wooden pole with any unduedownward pull or tension exerted on the screws by the straps with anytendency on the part of the pole to tilt or deflect transversely oracross the right of way along which the poles are distributed. Thethreefaces, a, a, a, to which the stra s 1 are anchored on oppositesides of the fiices b are disposed substantially parallel to the generaldirection of the wires to, the latter, as well understood in the art,being usually secured to the cross-arm 5 carried by the pole, the faces6 being practically disposed in planes transverse to the wires to orparallel to the cross arm 5. It is perfectly obvious that should thepole P for any reason (as for example in consequence of wind or otherpressure) tend to deflect or tilt in either direction across the rightof way or across the line along which the poles are distributed, thestraps 1 anchored to the members it of the reinforcing bars 2 wouldexert proper tension on the securing screws 3 and thus maintain the polein the Patented Nov. 3, 1914.

rigid and upright position to which it was originally set on the base B,the blocks or plates 4; preventing the screws from sinking or workinginto the wood of the pole (a result which would be attended by acorresponding loosening of the straps). If the pole tends to deflecttransversely in one direction, one set of straps and anchors would actas tension members, and if the pole tended to deflect in the oppositedirection, the other set of anchors and straps would be brought intorequisition, the faces 6, b, requiring no straps for the reason thatthere is substantially no tendency for the pole to deflect in planesparallel to the general direction of the Wires w.

As indicated above, the invention is not restricted in its applicationto electric-wire carrying poles, and I may with equal propriety apply itin connection with the ordinary fence F, as shown in the modification inFigs. d and 5. In that case a four sided base B may be employed, the twofaces, a, a, which are parallel to the direction of general dispositionof the fence carrying the straps 1, the contiguous faces 7), I), havingno straps. The straps are anchored to the hooks h of theconcretereinforcing members, and secured to the post P as fullyindicated in the drawing.

From the foregoing it is obvious that the fence cannot be deflectedlaterally, being tied securely to the base B by'the straps l secured tothe post P resting on said base. The term pole-base is to be consideredin its broad and generic sense, and is intended to cover any base towhich any upright post, strut, or any member Vertical, iorizontal orinclined is secured against deflection across a central axis of thebase.

Having described my invention, what I claim is 1. In combination with aconcrete base provided with reinforcing members penetrating the wallsthereof and projecting outside said walls below the top thereof onopposite sides of a central plane through the base, a pole resting onthe top of the base, straps passed over the projecting portions of thereinforcing members aforesaid and secured to the basal peripheralportions of the pole, for preventing deflection of the pole across theplane aforesaid.

In combination with a concrete base ovided with reinforcing rodspenetrating plane through the 40 he walls thereof and terminating inhookto projections beyond said walls below he top of the base and onopposite sides of a central plane through the axis of the 5 base, a poleresting on the base, straps extending across the pole-supporting surfaceof the base, and having their lower portions passed over the hooksaforesaid, screws for securing the upper portions of the straps to thepole, and reinforcing blocks embedded in the pole and engaging the outerends of the screws on the side facing the pole supporting surface of thebase, the parts operatingsubstantially as and for the pur- 7o pose setforth.

In testimony whereof I afiix my signature, in presence of two witnesses.
